Chuck McCann guest stars as Tinker Jones, a mute, itinerant coppersmith. When he wanders into Walnut Grove, Tinker also finds himself in the middle of a community tiff over purchasing a bell for the church. Haughty Mrs. Oleson (Katherine MacGregor) offers to purchase the bell, but only if it is "dedicated" to her. Without saying a word, Tinker neatly solves the dilemma. Featured in the cast is a very young Sean Penn, the son of episode director Leo Penn.
